I feel betrayed!

Almost 1 and half year ago I married an indian girl ( arranged wedding) after three months off marriage with have had sex only once in such a time, my wife complaint of swollen fimgers called chilblains. Before marriage she had not informed me but to my surprise when I read about its consequences of such a health issue I was shocked to know how its stays forever , with no cure to this problem. And then she said she has had it since child hood and since this problem surfaces in winters only, we had arguments over what I would do with her problem if its life long and I reside in canada - whcih they knew but hided the disease.

All my. Cncern is did she do the right thing by not telling about a life long. Health Issue before marriage.?

Now after seeing her and her dad health extremeties in winter, when she is not able to work due to swollen hands and feet, she is unwilling to dissovle this marriage as I don't feel trust towards the relation anymore. Also is it right that she knew I am canadian and life in canada is not so simple where weather is much colder than india.
